Drupal 7.x

I had problems in with a Drupal 7.4 install where cron stopped working (crontab and manually). I wasn't able to update modules (MediaGallery) and because of some incompatibility with the Media module decided to update to 7.7. After the update which was finished without errors (1 notice, 1 warning) i tried to run cron again, which didn't work. When trying to update modules i get the same error as before:

I wanna make a view of some ads which each has an image and a link.
So as the default behavior by clicking on the image, it used to go to the link.
Thus I create a content type by an Image & a Link field, but don't find any way to just view the image and instead of linking it to the content, attach it to the link field I created before.
How could I made it?

Thanks for your time

How to switch off the Warnings ??How to find the concerned module(s)? (deactivating "filter" didn't change anything and couldn't be a solution anyway.)

Hi,

I'm planning to use Drupal instead of Wordpress on my interactive project. According to the plans, there will be 10.000 registered users on this year. Can Drupal meet this demand? Or what problems am I have to faced on this time?

I've built a Drupal site and added taxonomy terms to better set my blocks using views and such. The site had a crash of sorts(due to a module installation) and I had to re-enable all the modules and when it got back up my taxonomy link only bring up one of post associated with that term??? I don't know what is going wrong.

I recently updated to 7.7 and the problem still persists...

Need help..

Thanks to all who reply in advance.

For the past two days I've been dissecting the Marinelli theme so that I can wrap my head around theme development. I understand most of the code only I'm having difficulty understanding how do I change the banner slide to another jQuery image slide? I believe it currently uses Cycle jQuery plugin but let's say I wanted to use any of these animation slides http://vandelaydesign.com/blog/web-development/jquery-image-galleries/ for example. What file do I start to update or override or alter?
