No problem. Open you file in PS. Change the format to .tiff or .psd and SAVE. (Please note the following "words" are translated from Danish and may not be totally accurate)
In "Image" choose "Image Size", and a little box will open At the bottom chose "bi-cubic" and mark both "keep aspect ratio" and "new data" (this last one is VERY important, without this new pixels will not be calculated). Now change resolution from let's say 72 to 150 pixel/inch (ppi). As you do this, the total number of pixel will increase (app. 2x2) as well. Click OK. Your file size has now changed to a larger file. SAVE, if you want to, with a new name (to keep the original). Do it all again. This time change 150 ppi to 300 ppi. Then reduce total number of pixel to the desired size (i.e. 5100x3400). Click OK and save. You now have a photograph sized i.e. 5100x3400 pixel to be printed at 300ppi. If you want to know the print size (for 300ppi): Click the magnification glas. Then click show print size in the top beam of your screen. The computer screen will now show the printed size. You may now compress in jpeg if you like - but keep the tiff/psd. Some of my colleages says I should not click the "new data" box until the last possible moment, because I shouldn't alter the pixels before I know how much is realy necessary. I don't know - I always did like described above. Just keep in mind from the start how many pixels you really want in the end. Hope this makes sence.
