I am trying to get some svg graphics drawn on my Drupal site and I've tested everything out on my local machine, not in a drupal site, just standard .html file and .js script and everything works great. When I want to use it with Drupal, I've tried using the module Raphael with my.js file but it says that Raphael does not exist so I tried the scripts[] = js/raphael.js from my theme's .info file and I get an error saying that f is null, whatever that means. so I guess my main question is how can I get the code below to work in my Drupal site?

Is it possible to change content within a non-content region/block depending on what page you're viewing?

For instance, I have a bunch of feature pages. Each page has a sidebar that I would prefer to style globally as a region (forgive me if I'm still using the wrong terminology), but I would like the sidebar to contain a list of items that change per page. What is the best way to get this functionality?

I can provide more info if needed. Thanks!

I have created an article with an image in Drupal 7.2, but the image does not show up on the finished page, or even in the preview.

If I go in to edit the article, I can click on the name of the file I have uploaded and I get a 403 error message in a separate window which says

"Forbidden
You don't have permission to access /drupal/sites/default/files/field/image/(name of my image) on this server"

Hello people!

Just signed on this forum, as I am a new member and haven't ever used Drupal.
I am thinking of doing so though, so before I start, I would appreciate some of your help...

I was approached to design and develop an e-commerce site for a small womenswear fashion brand.
The brand will produce new pieces each season as usual. Womenswear, shoes and accessories.

I have designed their main site, so we had a discussion about the shop the other day.
Unfortunately my knowledge regarding the matter is very limited, as I am more of a front-end developer with some basic knowledge in other areas.
I learn though, mainly through forums and tutorials (on the internet).

Looking into options on making an e-commerce site I have narrowed it down to three. I am sure there are more, but for now, i'm presenting three....

1. Drupal - which seems to be the most flexible - but would definitely require me to learn a lot of new things (valuable i suppose)
2. Prestashop - which seems kind of a risk, but easier to set up (maybe a lot more expensive)
3. Volusion inc - which I don't know much about, but I guess it represents a kind of e-commerce that has a monthly price and therefore should work like a charm.

Furthermore,
My questions regarding Drupal and e-commerce are :

I've scoured forums and tutorials, and I still can't seem to solve this problem. I'm trying to enable Clean URLs for one of the sites in my multi-site installation, but the checkbox in the admin menu won't appear (which I'm assuming means it's not properly configured).
