that's the skin's file, you can find many pics in it.
1. Change the pics of cool skin, keep name & size the same.
eg, change the new post pic.
the cool's new post pic '
newtopic' is:

and i create a pic instead of the cool's '
newtopic' pic:

, remember also named it '
newtopic'.
Note: keep pics' names the same, and also the size of the pics (the size can be a little changed,but dont change much) & name the skin file()
2. Upload the skin file (not rar,just the file include all pics of skin) to your free webspace.
for example: I create a skin named '
skin1' already, and i wanner upload it to the webspace now .
① Go to your webspace, in the
Root, create one file, named skin1, submit then:
Note: Create the file in your webspace's Root.
ok now, look at the below pic.
② Click in the webspace skin1 file, upload all the pics in the skin1 file on your PC.
upload already:
3 .Admin CP. --> Forums --> Skins --> add a new one . put the name in first, then submit.

4. Edit the skin1's detail to edit the skin.
Forum Logo {BOARDIMG},{BOARDLOGO}: put the logo's name of your skin. my skin1's logo name is logo.jpg, so i put the
logo.jpg in this textboard.
Image Directory {IMGDIR}: put the url of the skin in your space ,as my webspace url is:
http://ann1.91.tc, and my skin file name is
skin1, and i have upload it in my webspace
root file, so then 'Image Directory' is:
http://ann1.91.tc/skin1/.
Smilies Directory {SMDIR}: images/smilies (dont modify it).
The others you can modify it to what you want. (Sample for reference, download the
attachment)
