Preparing Images for the Website
Reducing Image Size for SAF galleries.
There are several methods for reducing image size (file size), listed are three methods that I have used, that work on a batch (group) of files at one time.
1. Resetting Your Camera
The easiest is to look in your camera manuel and reset the camera to take small pictures, 300 to 400 kb in size. Just remember to reset the camera back to its prior setting.
example: for the Canon SX200 – see Camera Manual pages 72-73. Try: M3 setting, normal.
2. Using Photoshop Elements
Create a new folder and place a copy of the larger images in the new folder. This will protect you original image form being lost.
Open Photoshop Elements.
Go to File-> Process Multiple Files …
Use browse to locate the new file with the larger images (source)
Check the box “same as source” and allow the files to be overwritten
Skip File Naming
In Image Size, check “resize images” and set Height at 640 pixels.
BE SURE that “constrain proportions” is checked
Set Resolution at 72 dpi
File Type: check Convert Files to: Select JPEG Max (or High or Medium)
Click “OK” to run.
I’ve always used Photoshop Elements as their Multiple-Files processor will retain the ratio of height to width. All I do is specify a maximum height.
3. Reducing a group of images in Photo Shop:
Place new images in a new folder.
In Photo Shop, select Files -> Scripts ->Image Processor …
Select the folder to be used
Select the destination – suggest you make a new folder
File Type: Select as jpeg
Use a quality of 10
check resize to fit
set both width and height at 640 px
Then “RUN”
With the Image Processor in Photoshop CS3 (I assume the others are similar) the program seems to set the width first and then the height, or it uses the largest dimension first. What works is setting both dimensions to 640 and accepting wide images will be smaller.
.
If you have a newer Mac computer there is a program titled “Preview” which which has a resize application under the heading “Tools” which will resize an image quickly. Look under “applications”.
