I seriously need some advice here. I have a tech-blog where I use some one to write articles for me. I'm really having trouble deciding the use of images. Blog articles without images looks really lame. I know I can't just steal anyone's image and put it on my site right? So I though I can just use the link of the image I need without uploading anyone eases image. I thought this would be good for the site I'm linking too as I'm giving them some link Juice!

Today embarrassingly I found that this technique is called "Hotlinking" :/ . Which is kind of stealing bandwidth if used without permission.

Can Some one shed light on this. Where can I find trouble images for my blog. Please note that as my site is mainly about newest technologies so free images usually won't serve the purpose..

Any word is welcome!
