Is there a way to try on the clothes on your avatar before uploading the textures?

This is my first time creating clothes here in SL and i'm wondering if there's a way I can try my textures on my avatar before uploading them. Thanks

When you select an image to upload, you should get a "Preview" window.

Right above the image, you should see something which says "Preview Image as".

Select the list next to this which corresponds with the type of clothing item you want to preview, and you should see it applied to an average avatar body. You can rotate and zoom the body with the Alt and Ctrl+Alt keys just like with the normal camera.

I wish there were a way to preview clothes and animations *on* our current avatar, but unfortunately we can't do that yet. It would be great if we could though =D

This is only when you upload ONE texture, though. I don't think you can do it with "bulk upload"

Use the Test Grid (SecondLife Test Server).
That way you can upload without having to use your inworld credits.
And you can test it until you feel its ok, then you can work on the actual original server.

near the bottem of the topic there's a huge post about how to do it without paying, I found it very handy ^_^

I just want to add, since I created that post, that the method I describe is in no way a cheat to get around paying the L$10 for the upload into SL. That ultimately has to be done if you want to sell the clothing or texture in-world. The method I describe is merely a preview.
