I just send you an email with the high resolution version of the template, so you don't need to worry about it.
Actually to change the resolution of the template:
1. Choose Image > Image Size.
2. Change the template resolution.
- To change the resolution and adjust the total number of pixels in the template proportionately, make sure that Resample Image is selected. Then choose an interpolation* method.
3.To maintain the current proportions of template width to template height, select Constrain Proportions. This option automatically updates the width as you change the height.
4. For Resolution, enter a new value. If desired, choose a new unit of measurement.
*Bicubic (Smooth) for the slow but more precise method, resulting in the smoothest tonal gradations.
I re-post here brief information to prevent layout rip when you add more text:
"...When you need to place more text in the template it is very important to add vertical alignment "top" for all tablesÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢ cells that contain pictures (slices). This will keep all the pieces (slices) of pictures together.
<td valign="top"> <img src="images/top1.jpg" width="770" height="99" alt="" /></td>
- valign specifies the vertical alignment of the contents of a cell, row, or column. You have to align the contents (images) to the top to prevent layout rip."
