Attached image files have disappeared

Postby NigelJ » Mon Apr 09, 2012 3:14 pm

Why have the attached image files disappeared from the site? Is this a problem with my computer or have the image files been removed?

No the files no longer display as images in the text, but as files to be downloaded. What has changed?

I can see some of the older images but not the new. Please tell me if you can see the one I posted to the components forum, under the "Re: Arduino Motor Control Project Help" thread.

I have posted a copy of the picture here as a test.
I do not see the image, just a place holder for the file. This is true of two of our computers, one running Vista, one running XP.

I can see that an attachment has been loaded to the site, but the image is not displayed within the text.
Has there been a windows update that could have changed my settings?
The Maplin upload options seem to have been changed. The option to upload and image has disappeared, replaced with the option to "Place inline".

It does the same on my computer Nigel. If you click the link, it brings up the image fine but it doesn't display it in the forum.

My computer did do some updates recently, but I've got no idea what it updated.

If it helps, it brings it up in the browser:

I'm getting this looked into with our Internet Team as this is not something we've changed.

.

If the main image is larger than 300px x 300px the attachment will display as a text link, anything smaller and it will display a thumbnail.

After further discussions directly with NigelJ about this today i'm unlocking this topic because as i dont think it is resolved like we previously thought. There still seems to be something slightly a miss worth investigating.

Some things to note:

Nothing has been changed settings wise at our end regarding images since we fixed the multi server issue previously but there does seem to be inconsistent displaying of images.

There is a limit on the display of images as maplin_admin has stated which would explain why many are not displayed but some larger files are being displayed currenly which is crazy

:-?

So what else could cause it? get your thinkning caps on...I'm going to continue to look into it also

I believe that there was a display image size limit defined somewhere in the FAQs. This limit was of the order of a 50KB file size.

I also think there was an option to load images separate to file attachments. I can no longer find this menu option. However, Just to check that it is not an figment of my imagination. I did explain this in option in a reply to a posting on this subject.

I have observed that images are switching between being displayed and being shown as file download links each time on log on. This is similar to the behaviour when different servers were storing the pictures. Not knowing how the Maplin servers are now arranged, I am speculating that maybe the different servers are applying different size rules to attached images. Such speculation is meaningless if Maplin now run just one large server.

The 300*300pix is I believe, the size of the text box that appears to tell the user that a picture file maybe downloaded. I think the 2000*2000pix is closer to the size of the picture than can be displayed in the text.

(The problem seems to be in the relationship between the image down load size and the pixel size of the final picture. This is not a simple relationship, as it depends on the compression used. It does not make sense to filter attached images based on pixel area, it is more logical to limit the image file size in bytes.)

I am going to search for the attachment advice posting I made some time ago.

Attached is a picture I have posted else where on the site that is visible within the text. Re-posted here, the image is replaced by a download tag.

Now tell me nothing has changed. Admin may not have changed the settings, but something is clearly different.

I suspect that the change happened during the last few days, as I am sure the last image I posted to "Components, Arduino Motor Control Project Help" was visible when I posted it. However, I can prove something has changed since the 13/3/2012, as this is when I last successfully posted an image to the site that appeared within the text and is still visible.

(Question: When did you last upgrade the site phpBB software?)

For your information the attached image is 408*306 pix and is 20.5KB .jpeg compressed.
The exact same image is visible in the text in: Suggestions and Feedback Anachronistic site rules.
It is not even the biggest image I have posted that is visible in the text.

I would suggest it would be better to define a limit on the attachment file size, than it is to limit the size by pixel area. The latter is clearly not working, as the apparent size of the image in the text seems to have little to do with its reported pixel area, with large pictures sometimes posting as relative small size images, and the reverse also being true. I assume that it is the former you wish to control, as this indicates the disk space occupied on the Maplin server.

It is worth note, that judging from the comments at the phpBB web site, the issue of attachments and image files is a hot topic, with lots of fault reports.

Looks to be something with the 300x300 pixel rule.

I can vouch for this not being changed, it's very rare the admin panel is touched, as the forum is running absolutely fine at the moment.

Certainly something has changed, but it's going to take some investigation work as to what, I'm sure Dave and maplin_admin will be able to look into this, but it may take some time.

I'm afraid for now, it's a case of watch this space.

I have rescaled the OSD image to make it 265*219 pix and only 15KB

It seems that the file filtering has switched from file size to pixel area. While I accept that this filter option was defined when the site was initially set-up. The setting has only become active in the last few days, maybe as the result of an automatic reboot or as a result of the change to BST.

I still do not understand why the display image size seem to be unrelated to pixel area. Maybe the software is already applying a scaling function. I would not describe the above image as thumbnail size. By definition a thumbnail size image is one that can be covered by a thumbnail. As seen on my screen, the above image is approximately one quarter to one third the width of the text page.

It is also a mystery as to why some older images, that break the 300*300 pix rule, are still visible, while others are not. At first I assumed that the rule was only applied when the image was submitted, but this cannot be the case as it appears to be applied to older images. I speculate that it may relate to which of the old servers the image was up-loaded. Maybe there was an inconsistency in the file parameters appended by each server.

Again I suggest that images should be filtered on the basis of file size rather than pixel area, as the former is far easier for the user to adjust and it is directly related the storage space taken on the Maplin server, which I presume is the important parameter the site admin wish to control.
(For anyone interested in up loading pictures, I have used MS paint to scale the images.)

I request that if possible the Server software should be set to auto scale the image size to occupy a fixed pixel area in the text, sufficient to allow the image content to be viewed with reasonable clarity.

I hope that Maplin forum admin will report back on the image loading problem, if only to assuage my curiosity about why the Maplin forum servers suddenly started to process the image size limit instructions, which it had consistently ignored for the past twelve months.
