| Where does one begin on this confusing subject? |

Firstly before you do anything always make sure you are working on a copy of your photo, never work on the 'master' - the photo as it came off your camera. Place a copy (or copies) of your intended photo(s) to send to the website on your desktop. Photos that come off your camera can be in a variety of sizes, I've had all sorts sent to me from 640x480px (pixels) up to an enormous 2272x1704px and all sizes in between! The original photos from your camera, depending how your camera is set, will nearly always be at a very low JPEG compression ratio. This is to preserve high quality for personal printing. So an original photo of say 1280x1024px could have a filesize of around 500 Kb (½ Megabyte) - far to large to send, and for your webmaster to store on the server cost effectively. Photos that are published on the
website are resized and cropped to 800x500px and then compressed by a factor of
25% JPEG format, this gives them an average size of 75Kb each. Ideally any photo you send should
have a horizontal resolution of 1024 and at 4:3 it will have a vertical
resolution of 768px. This gives me greater editing power to ensure that only
unimportant parts of the photo are cropped off. Up to now I have been
talking exclusively about photos taken in Landscape format, should you
rotate your camera through 90 degrees and send in a portrait picture
then resize so it comes out at around 450x600 (3:4). |

Right that's the technical description - How do we do it? |
|
Firstly for those using Windows XP:-
You may or may not be aware of a "Powertoy" plug-in from Microsoft which makes the job extremely easy. First download the small (520kB) 'plug-in' from
the Microsoft site at: What this little program does it to add a choice "Resize Image" to the right click context menu. So... Copy the photos you want to send to the website into a separate temporary folder, left click one of them to highlight it and then hit Ctrl A to highlight all of them. Next right click on the highlighted list and
select "Resize Image" from the pop up menu. The utility will then resize and recompress the picture files before your very eyes, watch the filesizes shrink of all the highlighted photos. When finished upload the photos as an attachment to an email in the usual way to this website at the usual address. |

I don't use Windows XP:- If you are using an operating system other than XP, do not wish to install the very small Microsoft plug-in or want to do the job manually then I suggest using the excellent Jasc software "Paint Shop Pro" although many other programs like Adobe, Corel, MS Picture It, etc. will all do the same, once you find the right buttons to click! Paint Shop Pro is shareware and you can try it out for 60 days by downloading a fully working trial copy from the Corel Website (Jasc has merged with Corel) |

The tutorial below uses Paint Shop Pro and Paint Shop Pro was used to produce the screen shots! |

Step 1:
Working on the COPY of your photo - Load the image into Paint Shop Pro. Under the 'Image' toolbar click 'Image Information' this will bring up a dialogue box. As you can see the original size of my sample photo is 2288x1712 pixels - far too large! |

Step 2:
Under the same 'Image' drop down menu, select 'Resize' This opens up the resize box. Select a width of your choosing - in my example I have chosen 800pixels. Ensure the 'Maintain Aspect Ratio' Box is ticked the height will automatically be adjusted as you specify the horizontal resolution, and you do want your final image to look right - not squashed or stretched! Click OK |

Step 3:
Select the crop tool Keep your eye on the status bar bottom left for the final photo size as you are dragging the crop indication lines around. Once you have an approximate crop window you can adjust each crop line individually or move the entire box up/down by left hold clicking within the box. Once you have it right double click within the cropping box to crop. |

Step 4:
Having cropped the photo now to 800x500 we need to
save it. Choose 'Save As' select save as type JPEG Important:- Before saving click the Options button to open up the 'Save Options' box. Here you can specify the compression factor 25 is a happy medium between filesize and quality for the website. Click OK and go on to save your masterpiece! |
|
|
|
| That's it you've done
it. All that needs to be done now is to attach it to an email and
send it to the usual
address.
The example I used in this tutorial is a photo of a
little known 'locals' beach near to Santa Cruz on Tenerife, you need your
own car to get to it! Take a close look at the actual finished photo used in the tutorial - doesn't look too bad does it?? |
