Andy writes:: It might be  useful to everyone on the list if someone with
sizing experience
: could write a small tutorial on how to accomplish this effectively. The
process
: used or to be followed probably is software dependent I realize.

Resizing with Irfanview. (freeware)


place all edited images in a folder.


open any image int hta folder and press B on the keyboard (that means
'batch')


press the 'add all' button.


click the 'batch conversion' radio button (unless you wish to rename them
at the same time, in which case press batch 'conversion - rename' )


Press the options button to set the jpeg quality (select 'keep exif data'
if desired)


Tick the 'Use advanced options' box, then set those options.

Tick the 'resize' box and choose from:
set new size (in pixels) - you only need to set height OR width - set to
the maximum required
OR
choose from 'set long side' or 'set short side' to (in pixels)
OR
set as % of original

make sure you have the preserve aspect ratio box ticked, and note that the
resample function (as opposed to the resize function) uses the algorithm
selected previously..

At this same time on the right you can choose to sharpen, flip, rotate,
convert to greyscale, invert, adjust brightness, contrast, gamma,
saturation, colour balance (R,G &B), set a canvas size & colour, add
overlay text (such as ©), set the colour and relative position of the text,
create a subfolder etc  -make sure you untick the ones you don't want to
use! (if you like before you hit OK, save these settings to use again:)
Choose to create a subbfolder in which these images will be stored.

hit OK

hit start.

smile, job's done :)


example:
108 files, 196 Mb
set to 800 pixels width, use lancozs resample (slowest, sharpen 12, add
overlay text right bottom corner, save 81% quality.
time:54 seconds.



Alternatively for a single image, open and hit Ctrl+R and set the new size
in pixels

(if you want to add text, drag a box where you want the text and hit hit Ct
rl+T, type the text)

shift+S to sharpen (this defaults to the settings set under 'effects
browser' (Ctrl+E)

press 'S' to save as and set quality and location, as filetypes:
BMP,ECW,EMF,FSH,GIF,ICO,JP2,JPG,JPM,LDF,LWF,PCX,PBM,PNG,PPM,RAW,TGA or TIFF

Press 'I' to see the new file size, if you don't like this press 'U' to
undo and set another quality level then save again - repeat until happy :)

done
