OK. I have found the solutions to my two problems, thanks to Tom Cardoso. Thanks, Tom! I hope reposting similar information is not problematic; I would have killed for answers like this.
A couple of things I learned that may be helpful for others having trouble getting the random_full_background.php plugin to resize the background or limiting the plugin to the main page only:
(1) If you are using the expanding menu code, put the script that lists the numbers of windows that you close at the very end of your code, just before (/head). Sawatzki's instructions tell you to put the full_background.js at the very end, but when you switch them it works, at least for me.
(2) THANK YOU TOM CARDOSO! for helping me to limit the random full background to my main page only. The commented instructions in the random_full_background.php, while extremely helpful and organized, I think are actually wrong. Like Tom, I was also getting straight-out errors when changing that code. So to reiterate his advice:
- first, un-comment the code at the top, as per instructions
- second, do NOT un-comment the code at the end (the brackets with the 'else') keep it commented
- third, add a single closing bracket ( like this: } ) just above 'return;' so it should like this at the end:
}
return;
}
This should allow you to have a full random background on your main page only which resizes dynamically.
Thanks to all - and hopefully I am done with this for the time being!
