I’ve just installed the Gallery software (http://gallery.sourceforge.net/) and hit a snag: it appears that something called “exec()” is disabled. I’ve just written DH Support asking them to enable it for me, but since it’s New Year I don’t know what response time to expect, so I would like to ask you for thoughts and comments.
Do you think DH will enable exec() for me?
I have no idea what it is, technically speaking. I just installed the software - I didn’t write it. If DH won’t enable this, then I basically can’t use the software, which would be a real loss to me. I wouldn’t know how else to solve the problem, or how to work around it.
C.2. I’ve installed Gallery and all seems well. But when I try to upload an image it says Unable to make thumbnail(0) or Invalid image. What gives?
A: This is a very common problem. It’s usually because the image manipulation program isn’t getting called correctly, and this can happen for a number of reasons. If the output displays exec() see FAQ C.29.
C.29. Why do I get this error: Warning: exec() has been disabled for security reasons?
A: Basically, this is a form of safe mode. Gallery requires functions like exec() to perform operations on images. The steps to “fix” this problem are the same as in FAQ C.5.
C.5. Whenever I try to upload an image in Gallery, I get all these errors about safe mode. How can I fix this?
A: This is an unfortunate situation, because Gallery cannot run in safe mode. You have three options, listed below (try them in that order).
- Email your host asking them to turn off safe mode. They are providing a service to you, and safe mode puts severe limits on that. If they are a good host, they should listen
- Try FAQ B.3, where you can use PHP as a CGI. This is usually pretty difficult, if you don’t know exactly what you’re doing.
- Find another host that doesn’t use safe mode. Some are listed in the Gallery Hosting Referrals Page.
