error when adding random images

[addictedJen]

It's been happening for some time now.
When I add images through batch add files they sometimes don't add to the gallery and my whole site is showing an error for at least 30 minutes (not only gallery but my main site too). It's completely random - one image adds but the next causes the error.

And I have no idea why it does like that.

Well, you haven't posted a link to your gallery nor have you posted the text of the error message you get, so what do you excpect?

Sorry!

here's the gallery. it's Error 500. it says something like contact your webmaster etc. but please don't say me to contact the webmaster cause the error message shows my e-mail address so I guess I won't answer myself anyway.

Talk to your host. Maybe they auto disable your site if you overload it while batch adding.
