How to put lines on an image-make a picture glow-or make text look clear??

Hey all. I am pretty new to Photoshop and I have come across a few things that I would love to do but I cant figure out how to do them. Also, I have elements so I'm not even sure if I can do them. Anyway one of the things I am trying to learn is how to put lines over an image. For example the very first picture on this site:

Another thing I have been trying to figure out how to do is how to make the text 'clearer' on an image. An example of what I am talking about is on the last banner in the first post in this thread (the one that says bicycle buddies):

And the last thing I can't figure out how to do is make the image sort of 'glow.' An example of that is the first banner that says "natural beauty" and it has a pic of Jennifer Anniston on it. Keep in mind I'm not talking about the text glowing. The link-

Anyway, sorry this post has more than one question in it, lol. I would really appreciate an answer! Or maybe even a few. Thank you!!

For the lines, u can use the line tool. adjust your line weight at the top. U can blend with the image by using the blending option under layer style. Just play around with the opacity.

For the font, there are a few styles for you to choose on the right. Choose a darker colour if your image is light to make it look clear.. unlike the one in the banner.

For image glow, u can use diffuse glow under filter -> distort. decrease the grainess level if u dun want any grainess.

hope this helps!
