Hey if in the future i want to sell or buy a texture, How can i send the pictures? I know send tc.

Thanks you.

Upload it to a website, such as tinypic.com.

After that type the image code around the image link.
[IMG][ /IMG]

You can also put it on attachments... Right?

upload the picture to something like photobucket
then put link to the picture

You can use it as an attachment, but its much easier just to go to a photo uploading website. The one I use is Tinypic. Just google tinypic, select the picture, and copy the link that starts with [IMG] at the beggining
