Thumbnails not showing up

Hi everyone, hi shaun,

I’m working with revolution 2.1.1-pl on a Linux-based shared-hosting server. I would love to use the Gallery plugin, but I am constantly running into problems somehow wink

I am pretty sure this is is due to my hosting environment. However, that can’t be changed soon so I’ll have to find a way around the problem.

Gallery is not showing any thumbnails, neither on the manager page (in components) nor on the frontend page through the gallery snippet. The thumbnails just can’t be created. Now phpthumb and GD and so on are definitly working and set up correctly, because the filebrowser can display thumbnails and creates them.

I know Gallery is using it’s own connector to call phpthumb, so this seems to be where the problem is. Gallery generates this to display a thumbnail:

/assets/components/gallery/connector.php?action=web/phpthumb&h=100&w=100&zc=1&far=C&src=http%3A%2F%2Fwww.my-domain.com%2Fassets%2Fcomponents%2Fgallery%2Ffiles%2F7%2F16.jpg

This is not! working.

In comparison, this is the call the filebrowser uses:

/connectors/system/phpthumb.php?src=%2Fassets%2Fcomponents%2Fgallery%2Ffiles%2F7%2F16.jpg&w=80&h=60&f=jpg&q=90&HTTP_MODAUTH=0&wctx=web&basePath=&basePathRelative=1&baseUrl=&baseUrlRelative=1

and this works! I tried duplicating all the additional arguments from the second call to the first call manually to change it to a relative url and call it in the browser, but that didn’t work either. So the connector.php does just go a different way then the phpthumb.php.

I know, that this normally shouldn’t matter and just work, but my hosting seems to be a bit funny. I already had to set the phpthumb_document_root manually, because my DOCUMENT_ROOT is not set as one would expect.

So, do you have any ideas on how to move on? Where (in which file) is the call to connector.php with its arguments generated? As much as I would prefer a solid, valid solution, I got to the point where I wouldn’t mind changing a core file to make it call phpthumb.php directly to generate the thumbnail.

Any help is very appreciated!

Simon

I forgot to add this: I think it needs to be a relative URL in the call, because php’s allow_url_fopen is turned off. It seems to run into problems with absolute URLs including http://....

ok, more information (concentrate on [34] in the debug array, I think):

Anyone any ideas, this can’t be unfixable!

OK, resolved this by setting gallery.files-url to files/.
Also this needs to be applied: https://github.com/splittingred/Gallery/issues/112

Hope this helps others:)

Thank you! Problem solved at last.

Be aware though, that this solution is still not very solid. For example, the [[+image-absolute]] placeholder also uses the gallery.files_url setting. However, that needs! the full assets/components/files path, because the script is running in the the document_root folder, whereas the working directory of gallery’s connector.php is in assets/components already.

Therefore, if you want to use [[+image-absolute]] you have to use something like .... src="assets/components/[[+image-absolute]]" ...
