Quick Sig Image Size Limiter

A fairly quick and easy to install hack that attempts to check the pixel size of any images users place in their signatures. If the image is above admin set dimensions an error is given to the user explaining the valid dimensions.

I've not found a simple version of this for v3 - apologies if it's already out there somewhere!

- This is purely a BETA release as the getimagesize() function used seems to fail for certain images on one test install, unknown reason at present. This will not make the hack fail, simply some images on some servers will be allowed even if over the set size. To prevent this uncomment the five lines in the added code to give an invalid image message instead.


The options to set the size limits for signature images will be found in the admincp vBulletin Options --> User Profile Options


*****PLEASE NOTE*****
I am unable to provide any support at all for this hack - sometimes it works, sometimes it doesn't.
My knowledge dosn't reach far enough for me to understand or fix the reasons behind it failing on some installs, sorry.
If it works for you, I'm glad, if it doesn't then just revert everything and try looking at the other sig option hacks, sorry - best I can do

I just found a problem with this. If sig limits are on (example 400 characters) and the sig is text only, then the system adheres to the 400 character limit. If there are images in the signature, than it ignores the limit, and allows sigs of any length to be posted, so by adding a single image to the sig, the member can override the character limit function.

Anyone have any ideas on this one?

Hmm, I installed this in 3.03 and it didn't do anything.

Works perfect in 3.0.1

Did you run the Queries? Because it's not like you replace any code for this, its simply added code, so I would think it should work with every version, which leads me to believe you didn't do the queries. :ermm:

I didn't have that problem. The character limit was still working for me.

Any way to make it so the images auto-resize if they're too big?

I have a question about this hack, say I upload the file 123.jpg and use it as my sig. Your hack approves it becaues it is under the max size. After the image is displayed, I make a larger image and reupload it with same name overwritting 123.jpg. Correct me if I'm wrong but if only the UserCP can check the size again there is no way to limit someone from overwriting the file.

Alright, a couple of problems... I uploaded the hack to 3.03, if I try to upload a sig that's too big it gives me the error, but it didn't make any changes to the existing sigs that are too big. Any thoughts on why this is, what I can fix, or what a workaround is so I can get all my users to go change their sigs?

Also, when installing 7thgenCivic.Com's weight limit hack, I was returned the following error when I clicked on Edit Signature:

Parse error: parse error, unexpected T_IF in /home/file/public_html/bb/profile.php on line 1339

Which is the line:

if (!$image_size[2])

Any suggestions? Thanks!

i thinku got some messed up code somewhere. only thing i can suggest as it does work.

btw: only way to make all users comply is to delete everyones sig and make then start over.

Hi, quick help with this. I attempted to install this hack (my first hack) on a test board. I ran all the queries, added all the phrases, and added the code into profile.php, making sure to use the corrected and updated code, including the image weight option. The admincp options showed up, however, now signatures do not show up in threads at all. I noticed this while checking to see what affect installing the hack would have on an existing sig image that's too big, so I did not check to see if the hack actually limited the size of new sigs. Once I noticed that sigs were't showing up, the very next thing I did was replace the modified profile.php with the backup I made. But even after doing this, sigs still don't show up. What's going on?

Edit: Hmm, upon further testing, it seems that it might be working correctly afterall. I think it was a matter of one signature having an image that's too large, and anothe ID that didn't have a signature to begin with.

But it seems I'm having the same issue as dfaonxa above. If I install the image weight code, going into "Edit Signature" returns an error.

Oops, where's the :slap forehead: smiley? Misread of the image weight mod, didn't notice that where it says,

find

				if (!$image_size[2])
				{
					eval('$errors[] = "' . fetch_phrase('attachnotimage', PHRASETYPEID_ERROR) . '";');
					$preview = 'true';
				}

that the "find" isn't code, but an instruction. It's all clear now. Well, just ignore me, unless you're dfaonxa, in which case, hopefully this will help you solve your issue.
