So, it seems people are having troubles uploading images using the [img] tag. This problem does not seem to occur with any sensible boundaries, so I would just like to ask you to report any time that you try and fail to upload an image.

For example, I can upload mostly without problem, but the image http://img812.imageshack.us/img812/8642/sensun.png will not upload ("MySQL server has gone away" error). Have not been able to reproduce with any other image.

uploaded it with no trouble.

finally got one (yours).
I wonder if it's something to do with the filename?

Yeah, it's either the URL or some aspect of the image. I don't suspect filetype. My guess is the URL or the file dimensions are causing the error.

Have successfully uploaded images of larger pixel size and data size, so it's probably not that. I see nothing wrong with the URL itself; the filename is "sensun.png" - seems pretty normal - and other imageshack stuff has been done without error.

I just tried posting that image as http://img714.imageshack.us/img714/4752/suntest.png and http://img155.imageshack.us/img155/5933/sentest.png and neither worked. There has to be something about that image or the URL that is screwing this up. Do other imageshack URLs work?

EDIT:


EDIT2
Looks like imageshack works. It has to be that image.

Yeah, the MySQRL pic was from imageshack too. The other thing I'm interested in with this thread is whether there are other images that have failed as well. People have been complaining of bugs; are there any other problems with [img]?

I can't upload it to tinypic, it's too big.

It's definitely imageshack and the size of the image.

I'm doubtful if it's the image itself. This is a compressed version of the same image, which won't post.

The URL rockz just posted, sensun.png... I attempted to preview that as an IMG tag and got an SQL error:


The problem is clearly with the thumbnail code, the code that checks an image's size and if it's too large, writes out a JS-enabled IMG. But why would that fail to function?

We should try to narrow this down. Is it a problem with the image simply being too large, or is there something about that particular size or range of sizes?

It's most likely any picture larger than 425 pixels. Let me test...





Nope, hm.

Interesting to note that for a period of time, I was unable to post the first image without an error. It works now, apparently.

EDIT> Test 4500x2234

It's the images themselves.

http://farty1billion.dyndns.org/sensun.png - Saved the image from imageshack into my server.
http://98.202.196.115/.png - Not the filename
http://farty1billion.dyndns.org/shakurastiles2.png - Original image only from my server. Doesn't work.
http://farty1billion.dyndns.org/Psi.png - Original image only from my server ... but it works

Thats what I've been thinking. Here are the images from the thread I was trying to post when I originally found this problem, I don't have time to test them but I believe at least some result in the same error:

Might not be the problem, but I'm told it's not good practice to store images and such directly in the database (as BLOBs or whatnot) if you have the option not to. Storing the images to the file system and referring to them by their address in the database is more preferable.

Might consider that for both a speed improvement and a possible fix.

I don't think that anything on SEN except for maybe the file upload functionality does that. It would be a good speed improvement except that I don't think there's anything on SEN where that change isn't already in effect.

Incidentally, I rarely post images in my posts but I've been getting this error all the time, randomly, since it began. I just refresh and it works.

SEN doesn't store images in the database.


I think the problem isn't really the images themselves, but they take a little longer to parse or something. It seems the connection time allowed is just on the edge of having issues and the images sets it off.

So it might be some recently implemented inefficient code that is slowing down the parsing?
Because it worked fine for years, images or not.

The function called to get the image size might be a fairly recent addition because it would provide information necessary for thumbnails and resizing.

The slow function is getimagesize. It's a PHP library function and it can take as long as 15 seconds to return for the large image that's causing problems. Most images parse faster, but the call was probably always there. I suspect one of two things happened:

1) The timeout on the SQL database was lessened (15s seems a little short)
2) Something about this image is abnormal as far as being parsed by getimagesize. The delays are additive, so will likely encounter a similar error by including lots of images in your post (an average-size image takes a little less than 1s to parse)

This would be my guess. It could be possible the script is waiting for a response from the server? And during that time the SQL connection times out.
