I've got my signatute image on my personal webpage, but I fixed up someone's sig this morning, using the image in their gallery here on EquiSearch, so you can use any image.
If you would like to upload your signature image to the gallery here, you can do so, having made sure it meets the size guidelines we have set up.
To create a link to it in your signature, go to the picture itself and right click on the picture.
Select Copy Shortcut
Then go to your My Horse Space page and select the About tab and go to the section where you will enter your signature.
What you are going to be doing is creating a line of html code which tells Internet Browsers where to find the image you want to display as your signature.
All html tags have to open with a < you can make that by typing shift comma
The code that tells it which image to display is IMG SRC= (image source equals)
Then you have to tell it where to find the image, and that's the http://etc part of the code. You can put that in there simply by pasting the shortcut you copied in while you were in your gallery on the picture you want to use.
The url or address has to be enclosed by quote marks, so just backspace along till your cursor is between the = and the http and insert a "
Then forward space along to the end of the address and put another "
Then type SHIFT period to make a > which closes out the html tag and tells the internet browser the line of code is ended and it can go do what it is being programmed to do!
IMPORTANT: You need to have the " at the beginning and end of the address/url of your image and the entire thing has to have the < at the beginning and the > at the end, and the ONLY gap should be between the words IMG SRC, the rest of it is all mooshed together, no spaces, or it won't work.
I don't have pics on Photobucket, but I think if you have your pics there, it actually gives you code that you can copy and paste the whole thing into the signature box in your My Horse Space and that will work to display your image.
But my point is, you don't have to use photobucket. As long as you create the html code correctly, you can link to a picture anywhere and have it display in your signature.
I know this was a bit long-winded, but I hope it make sense.
I'm headed home now (I'm at, um, work, at the moment *cough*) but I'll check in again later and re-read this to see if it makes sense.
