Set a max file size of images in forum

Regular Joined: Mar 26, 2006 Posts: 63

I found a forum mod a few years ago that would limit the pixel size of images posted to forums with bbcode. If the image was over the max, it would resize it and create a "thumbnail link" to the full size image.

I searched and searched for this today but I could no find it. Anyone know what im talking about?

Doesn't the forum attachment mod that comes with RN do this?

Posted: Tue Apr 28, 2009 6:55 pm

Oh does it? My install of RN a year ago didn't have this. I had to add it manually.

Does it do what i'm talking about by converting the inserted image to a thumbnail and link to the full size image on-the-fly? Or do you just attach the images to the post with a link to the file without getting the thumbnail?

I personally don't use it, but that is my understanding, I could be wrong of course. Give it a test run and see. Wink

I got working a Forum resize image mod on my sites. With this mod all de img tags are limited to the width x height specified in admin panel and show thumbnail with a link to the full size image.

Try this, is easy and works very fine: Only registered users can see links on this board! Get registered or login!

Install with care in RavenNuke some bbcode.php modificatións not match the "search" instructions, but you can compare and only add the required changes.

The attachemt feature in "forums" will do this, but only for attached images using that feature.

Forums => Attachments => Management => Attachment Filesize Settings

Yeah, I played with those settings a bunch but I think my theme is keeping it from working correctly.

I cant seem to get registered on that site. I never get an email. Ive pretty much given up on the attach_mod in phpbb2. Its just not working for me.

Re: attach_mod

Make sure when you upgraded to RN 2.30.01 that you also ran rndb_upgrade.php located in the /INSTALLATION directory as this will install the new tables required for the attach function.

Posted: Sat May 09, 2009 7:55 pm

This was a fresh install. Was that part of the fresh install steps?

Posted: Sat May 09, 2009 8:16 pm

In the forum configuration under attachment, anything you click on should bring up the preferences page(s) with no errors. If no errors then the tables are installed ok. In the management screen, attachments should be "enabled".

In your RN root directory, temporaraily rename the .htaccess file to .htaccessBAK and see if the attachment functions ok.

Also, just what is the problem, any errors or the images don't resize with no indication as to why not, etc.

Ill try the htaccess change.
I dont get any errors, images just never resize and link...

Ok, You can get the file --> Only registered users can see links on this board! Get registered or login!

Also, you can view the mod working --> Only registered users can see links on this board! Get registered or login!

Perfect. That looks just like the one I used in the past. Thanks a TON!

Giving the attach mod a second chance.
I have changed themes and the attachments work correctly.
When images are attached (from the users computer) the image shows up as a thumbnail, and files show up like files like they are supposed to.

So now here is my question.
Is this mod "designed" to thumbnail images posted with bbcode where the image is hosted on another site like photobucket?
That was the main reason I wanted to get this mod working, but if it doesn't do that anyways, I'd like to know.

Posted: Wed May 20, 2009 8:18 pm

no it wont alter images hosted elsewhere, only files attached to forums

Posted: Wed May 20, 2009 8:57 pm

Dang it. Then it has been working like it was supposed to this whole time. lol
Ill be using the 3rd party mod above for this. Thanks!

OK so here is the change code for that mod.
However, there are a few discrepancies in this code and in RN.
Can someone revise this to work with the current version of RN.

Code:

This is a great addition to the forum!!
There is one thing to fix: width is updated when changed in the fórum general settings, but the height keeps the same value set on the first insert in sql!!
cheers

I just added

Code:

.postbody img{max-width:700px}

to my ravennuke.css and any image posted in the forums will not be any larger than 700px wide and the height scales to the width.

Posted: Fri Feb 17, 2017 5:34 am

I'm trying to get attachments to resize but none of the above are working. Any suggestions?

registered · Site Admin Joined: Jun 04, 2004 Posts: 6437

I'd suggest the CSS approach to limit the size. It won't resize if the image is smaller than the limit. You'll also need to refresh the page to load the new CSS.

Posted: Sat Feb 18, 2017 5:57 pm

It appears that the do not resize in some themes, some the do.
