How to increase image size in PS

I have been given several background image files which are 100 x 100 pixels. How can I resize these without losing resolution etc so that I can use them please?

You can always downsize without losing resolution, but as far as I know it is impossible to upsize and still retain good resolution.

There are programs such as BenVista PhotoZoom Pro or the free Smilla Enlarger that can do a pretty good job of filling in the missing pixels if you’re enlarging an image by a modest amount, but if you want to go from 100px square to 3600px square then you need to create nearly 13 million pixels from an original image containing only 10 thousand pixels, which is clearly going to be a bit of a challenge!

That is an extremely small image unfortunately .... rule of thumb is you can increase by 10% three times ... I've created my own action to do it ... 10%, then 10%, then 10% again ...NOT 30% all at one time .... that will give you a bit more but they would still be very tiny ... about half an inch on your 300 ppi background...

I wouldn't upsize from that small an image...


Upsizing all the way to 12" square at 300dpi would be a bit of a stretch (if you'll excuse the pun!) but Wendy may not need these images to be that big. I can get a decent result by resampling Wendy's avatar image from 72dpi to 300dpi, using one of the standard settings in PhotoZoom Pro, but in this case the original is 200px square rather than just 100px square. How well it works is going to vary quite a bit, depending on the nature of the image.

Thanks for your replies. Didn’t think it was possible. I don’t know why they have been made so small, not even seamless which would have been useable.

Where did you get them from, Wendy? It seems odd that such things should only be available at that small size! Are you able to share one here to let us see whether anything can be done with it?

I was told they came from Deviant Art, but I'm afraid I don't have them now as I have deleted them all.

if Deviant Art is sharing an image it's usually high res ... I wonder if it was screen shots or thumbs for display on images you had to go elsewhere to get ? ... next time maybe drop one into Google images to see if it can come up with it .. it could lead you to the originals
