Image thumbnails in MODx browser

I moved a site that was in development onto a server so that the client can populate the site. Currently the domain name is on a shared hosting plan and has the username alias (http://sheridan.liquidweb.com/~clientname/) while the client transfers content into the site – is it possible that the ~ is preventing phpThumb from generating thumbnails?

I created another fresh install to make sure it wasn’t an issue with a path in the config and had the same issue. I downloaded phpThumb and did the default demo that comes with the package and it seems to generate the images fine. The server has GD 2.0.34 installed and is running on php 5.2.13

I deleted the phpthumb folder in the core/cache – the folder is regenerated but does not have any subfolders.

I am lost on what else to check, any suggestions or ideas?

I am having this same issue with another site at the temporary URL – confirming that it is likely because of the ~ in the URL. Is there anyway to fix this so that the client can see the image thumbnails during the process of populating the site? Here is the error in the error log:

[2010-08-26 17:11:20] (ERROR @ /~clientname/connectors/system/phpthumb.php) Error outputting thumbnail:

Thanks!

Hello Waldus,

Did You found the solution ?

I’m having the same problem ...

Hey Luke,

My issue, in both cases, was tied to the aliased name in the URL as I suspected – /~clientname/. I had the client point beta.theirurl.com and it fixed the issue.

I figured this is more of an issue with ImageMagick and not Revolution, but if any of the developers read this and that’s not the case, let me know and I will file a ticket in Jira.

Just to keep everything in the same place, I just got this related error:

[2012-12-31 13:58:19] (ERROR @ /connectors/system/phpthumb.php) phpThumb was unable to generate a thumbnail for: /home/zzzzzzz/core/cache/phpthumb/phpThumb_cache_zzzzzzzz_srcf8857..0cd_par...e4_dat13..52.png

I'm not using a tilde anywhere. This isn't a production site and I just have a few pages. I think something in the Manager generated this, maybe when I went to view package info.

Getting the exact same error myself in a Cloud dev site (image TV's aren't working at this site). I don't know what I was doing when it happened. Will watch closer now.

Oh, and also a ton of these:

and

The errors I reported above stopped occurring not long after reporting. But today I added a number of images to the site and now the error log has a slew of them again. Maybe the clue is here:

...phpthumb.php ...OutputThumbnail() failed because !is_resource($this->gdimg_output) on line 557

OK, so "something" is not a resource. I don't have any of my images set as resources, didn't think it was necessary.

Is that any clue about what's happening?

Thanks.

Resources are stuff that the browser can request; this includes MODx resources, but also .js, .css, image, and any other files. Hence URL - Universal Resource Locator. That's why MODx started referring to what we used to call "documents" as "resources".

It's possible with the sudden influx of a lot of images to process, or perhaps one excessively large image, phpthumb is running out of memory, and not properly generating the image files to be written.
