Blank screen when uploading picture

[snw]

When I upload a picture > ~400Kb I get a blank screen (at upload.php). I can upload the same picture with lower JPG quality (22Kb) without any problems. The maximum JPG upload file size is set to 2Mb so this shouldn't cause any problems.

I can upload a PDF file of at least 1Mb without any problems.

What causes this error and how can I fix this?

Sounds like a problem with GD and your PHP memory limit. You need to either ask your host to allocate more memory to PHP, or install ImageMagick and use that instead.

We own and manage our own server . IMHO all settings are okay. Doubling memory limit to 16M doesn't help. Increasing the execution time till 900 doesn't help either.

Server settings:

• Server Type Linux
• Web Server Apache v2.0.54
• PHP 5.0.5-1.dotdeb.1
• PHP Max Post Size 8.00 MB
• PHP Maximum Upload Size 50.00 MB
• PHP Memory Limit 8.00 MB
• MySQL Version 4.1.15-Debian_0.dotdeb.1-log
• MySQL Packet Size 16.00 MB
• Maximum execution time = 30
• Maximum input time = 60

GD settings:

• GD Support enabled
• GD Version bundled (2.0.28 compatible)
• FreeType Support enabled
• FreeType Linkage with freetype
• FreeType Version 2.1.7
• GIF Read Support enabled
• GIF Create Support enabled
• JPG Support enabled
• PNG Support enabled
• WBMP Support enabled
• XPM Support enabled
• XBM Support enabled

Brian - are you trying to tell us that it's ImageMagick or nothing??? I've just installed Gallery onto an unhacked vB3.5.0 Gold release, I am seeing exactly the same problem as SNW. There's nothing in the Apache error.log, nothing in the debug vB php warnings log, nothing in the actual server logs.

The response is instant, there is no delay or wait, there is no output on the page. PHP is 4.3.2, with GD support and GD version 2.0.12 (compatible) enabled. All standard stuff, our own server, very lightly loaded, more than enough grunt to handle a simple image. It looks like you've got a problem with the error trapping, the image I tried it on was under the file size limit but over the pixel limit, it was a standard .jpg. Upload something within the limits and it works fine.

Kind Regards

Generally a white page like that either means that the image is larger than the PHP max upload size, or that there isn't enough memory for GD to resize the image. If that's not the case though and you'd like to submit a support ticket via the Members' Area here then I'll be glad to take a look at things for you.

That should not be a problem when the option 'save original image' is checked. I'm also using unmodified gallery files (vB3.5 Gold Gallery v1.0.1) except for the inline playing of media files in functions_gallery.php.

Brain, if you like, you can use the usernames provided in the support ticket to access the server.

Thanks Brian

I'll check those out when I get the chance, I'll up the pixel limits and see whether it loads. Pick up my URL from my account, I've enabled public phpinfo for you if you want to give it the once over. If you've got a support ticket from SNW I'll leave you with that one, I've got a test instance you can play with if you need a second example.

When I click on "Upload" after updating to 3.5.1 I am getting a completely blank page. This is before I've even done anything (just clicking the upload link).

Hi Brian

Some more information for you : Our php upload limit is 512KB, I can't enclose the file that is giving me problems, it's a standard .jpg 126KB 1280x960 image. Our gallery limits are set to 2MB 600x600 for .jpg's.

When I upload with those gallery limits it's giving me a blank screen instantly. If I change the gallery limits so that it's big enough I can see it upload (you get the delay) THEN it gives the blank upload screen. It's not getting as far as creating the image in the filestore.

HTH

Has there been any progress on this one? Has anybody found out what it is and can suggest a fix? I've just upgraded to vBulletin 3.5.1 and the bug is still there. I have a newly purchased and install Gallery that my users are complaining about, unless we fix this soon I'm going to have to switch it off

More than willing to raise a support ticket if needed, just say the word.

i am also getting the same blank screen when i try to upload via the batch upload
before upgrading to vb3.5 / 3.51 everything worked fine

OK, will do if nothing posted on here that tells us what it is. I just need to set up the FTP account for you, may take me a day or two to organise that.

Any updates from PhotoPost?

[KW802]

SNW, the support tickets were not carried over so we're going to need to take a fresh approach.

My GD settings, at first glance seem to be the same as yours... if you'd like send a copy of the picture causing the problems to kevin@photopost.com and I'll see if I can duplicate the problem on my server (I'll temporarily switch from IM to GD for image resizing and then upload the image).

I'm having the same upload issue...receiving blank page if image is large

[Chuck S]

Your would need to specify how large is the image?

PHP by default is set to 2M so if the file is larger than this then PHP bombs out.

If your PHP memory which by default is set to 8M and your using GD then it could bomb out on large files

At the top of your upload.php file you could try placing these to override PHP's setting's

The size is about 500k, i'll try that to see if it helps. thanks

[swa]

that worked! thanks!!!

[Chuck S]

Not a problem swa.
