Adding style sheets

Hi,
I want to use photos from Piacasa Albums in my site. When i used drupal 6 it was a modules which allow to use one Picasa account. Now this module don't have version for Drupal 7.

Perfect situation it will be, when each member of my site could add as a node link to his/her picasa album.
Any chance for this solution?

Is there a simple way/module to set conditions on fields upon edit?
e.g. if a checkbox is marked, an image is required, if a boolean is set, x is required etc...

Hi everybody,

I based my module on the ajax examples to make a multi step form.
In these examples, we can delete the last content of contents added dynamically.
But, i have to delete several content in one click, and this is my problem...
The form load the data in the form from database, and my delete submit, i delete the content checked. Until now, everything is allright.
But, the data in the form is still the old one, i have to reload the page to see the changes.

My website http://guofou.com
And I want to know is drupal 7 ready for a product site now?
I saw there is a lot of modules are beta , even the most popular module Views is beta and has some bug I meet.

Hi,
I've just upgrade to ubuntu 11.04 and my site which wirked perfectly yesterday on localhost do'nt have any acces to the third-party modules anymore, nor the themes.

It seems that everything that I copied to sites/all/ is not visible.

I've just downloaded the last version of a few drupal standard modules and I can't see them in the list of modules in the administration area... ?

What's wrong ?
Thanks !
