First thing to do is find you a picture or if you already have a loge that's fine too. Make sure you download it in a program like photobucket so you will have a URL code for the image. Or if you want to use a pic from the web, then all you have to do is right click on the photo and click on property and copy the URL code of that pic.
This is the code you will use to post on your blog.
Here is an example
don't get scared, all you do is replace the high lighted section with your info. Make sure you stay between the quotations.
Next step involves the use of Photobucket, if you don’t have a Photobucket account, go get one, and upload your image now. Once you have uploaded your image click on it, select the "direct link" option. replace the high lighted section with your image code. remember to stay in the quotations.
and that's all folks, you now have a "Grab Button" to place on your blog and for others to use on theirs.
If you have any question PLEASE comment and I will try my best to help.
Tip: after you make your code, save it on your computer so you can use it for other projects
