| 267505 | 2004-08-31 11:03:00 | i have recently found a new site on photography and posted a pic on it. and found they edited it as it was way too big....sigh.... how do i make a photo 600 megapixels wide? how do i measure these images before i post anything else? does a editing programe tell you this sort of info? the site quote says this..... "Photos should be no more than 600 pixels high or wide, whichever is the longest dimension. Photos placed in a discussion thread by the individual posting the thread should total no more than 100kb in file size. This can be 1 x 100kb, 2 x 50kb, 4 x 25kb or as many as you like so long as the cumulative total does not exceed 100kb." way out of my league here, any one able to explain or help me on this??? and then i spose it comes back to what editing prog will i use? thanxs beetle |

| 267506 | 2004-08-31 11:43:00 | Hi beetle 600 mega pixels wide is a wee bit to big. Do you have a photo editing program of any kind. If not, download irfanview as it is easy to use and alot of people here will be able to help you with it. |

| 267507 | 2004-08-31 12:14:00 | Hi Beetle If you are using XP Make sure you are viewing the pitcures in thumbnails, not list view, icons etc Right click on the photo and select Resize Options here (sal.neoburn.net) or if you click advanced you can resize to what you want. Rob |

| 267509 | 2004-08-31 12:31:00 | In most photo editing programs you have a dialogue box for Image Size..the parameters are usually pixel dimensions like width and height in pixel measurements,you set the long side of the image to 600pixels and then the width/height in inches or mm's and then the resolution which is usually measured in dpi (dots/pixels per inch)when you set the resolution for an email or web image you normally set it for 75 dpi as the computer monitor only sees images at that size..to set it any higher would be wasted..to print an image at full size for a deskjet printer you would normally set it for 250dpi but can go as low as 150dpi,if you try to print an image at 75 dpi you would end up with a jagged edge image but a monitor would display it perfectly.a resolution of 75 dpi plus 600pixels and saving as a jpeg quality 8 is not quite maximum quality but will keep the file size down to a managable level..try it and see.. hope that helps Keith |

| 267510 | 2004-08-31 12:33:00 | It bounced around here before, from my bad memory it should work with both Home and Pro, I can say it does with Pro | Rob99 (151) | ||
| 267511 | 2004-08-31 12:37:00 | sorry, one more thing, if the file size is still too big, try dropping the image size down, for instance don't send an 8inch by 10inch image change it to 5" x 7" or even 6" x 4" until you get the image accepted by the forum. As long a it is 75 dpi and say 500 pixels on the long side, you shouldn't have any problems with file size |

| 267512 | 2004-08-31 13:04:00 | Just a wee correction. Monitors and therefore webpages do not display in dpi, video cards cannot render in dpi, they have no meaning or function for the concept, they use pixels. However, scanners and printers do use dpi (dots per inch). Say No To 72dpi (www.scantips.com). If using an image/photo editor to resize just use "Constrain Proportions" to keep the image even and then all you need to do is adjust one side (heght or width). What software came with the camera beetle?, otherwise Irfanview does a pretty resonable job. Remember don't work on the originals but do work on them in other than jpeg format then save as jpeg to post as they degrade as you edit and save them. Cheers Murray P |

| 267513 | 2004-08-31 13:12:00 | Hey Murray Thanks for the correction but it is really not that important,what IS important is that people realise that they can adjust their file size by changing the resolution of the image ie DPI or PPI (pixels per inch) Keith |

| 267514 | 2004-08-31 13:20:00 | Hey again Murray just skimmed the page link you enclosed and found it very informative thanks..again it is mainly for people who are scanning images and does not answer the problem of file size reduction(that said I will try to attach web images at much lower dpi settings in future) Cheers mate.
