LBA hooks first pancake

In Photoshop use Bicubic resampling if you need to resize, it's the default so it shouldn't be a problem.

In later versions, if you have the option use Bicubic Smoother to upsize and Bicubic Sharper to downsize for the web whilst maintaining sharpness.

Finally, apply Unsharp Mask to the image.

An ideal size for this forum by the way is 800 pixels on longest side, 72ppi and a file size of no less than 200K, no more than 300K or so.

Thanks John,
I haven't got photoshop, just Faststone .
Will keep it to 800pixels for a better page fit !
cheers
