Help with resizing photos

[bass_junkie83]

I am having a bit of trouble resizing some images ready to send for print.

Normally i use faststone image resizer, but having read the guides on the printers website i don't think i can use this.

If you upload a 4"x4" image and choose the 6"x4" print size, your image will be stretched to 6"x4" resulting in cropping. The way to order odd sized images is to put the image onto a template whttp://www.talkphotography.co.uk/forums/newthread.php?do=newthread&f=19hich matches the print size, i.e. if you want a 4"x4" then you need to put the 4"x4" onto a 6"x4" template, flatten and save as a JPEG at 305dpi. The result will be that your 4"x4" image will be in the middle of a 6"x4" print.

I am trying to get some 10"x15" prints so i have created a 10"x15" canvas on photoshop and copied in the original hi res image. I then used the transform tool to resize the image to fit within the canvas and save as a jpeg of highest quality.

When i upload these i get a warning saying the images are only 72dpi. What am i doing wrong and how should i be doing it?

Create a new image in photoshop. Define the size as 10" by 15" and set the resolution to 300 pixels per inch in the new image dialogue. Then paste your original into that and use transform to fit it. Should make a 3000x4500 pixel image in 300dpi

That sorted it, never noticed that option before. Thanks for that.
