I have tried to ask this question on the contact page. I don't know if this is the correct forum to be asking these questions. I am also a Dialupper. So it is very frustrating.
Any suggestions.

Something about your posts or your account makes the anti-spam software start growling and so your posts get quarantined until a moderator gets to look at them. Unfortunately those sometimes get lost in a busy thread - I only spotted this post of yours by chance.

Apologies, but at least you are a step towards being recognised without the hassle in future.

ps. for anyone who thinks the filter is too aggressive, take my word that you wouldn't like the site without it. False positives are regrettable and a few spam messages get through but at least the forums aren't flooded with spam.

I only found this because Sime posted a link. I still can't figure out how to get there from the Home page.

From the Forums

This diagram shows the interaction between viewer (that use internet browser such as IE, firefox etc), DPS Web site (server), and Image Source (such as Flickr). Whenever there is interaction, there will be bandwidth usage between the two interactors. This diagram has been simplified for easier understanding. The numbering in the diagram shows the sequence of interaction, from top to down.

1) When we browse DPS website, a web request will be sent by IE/firefox on behalf of you for the web page / URL.

2) If the webpage is up and available, the DPS web server will give response to your IE / firefox. And your IE/Firefox will start download the web page WITHOUT Images. This is that minimum bandwidth has been used in DPS Web site for this interaction.

3-5) Once your IE/FireFox read to the point of img src="http://.... flickr", your browser will request and download the image from Flickr. Here, both the viewer and flickr bandwidth involved. As the image is much bigger than the text (see 2), then the performance of viewing a DPS website depends greatly on viewer's and flickr bandwidth, and very less depending on DPS server bandwidth,. The IE/Firefox will display the image bit by bit when downloading the image, depending on their behavior. However, this is untrue if you attach photos to DPS server.

In conclusion, those who upload photos in Flickr or other web server (e.g. nikonclub etc), very little bandwidth of DPS server will be used that will not affect the performance of viewing by other DPS users, SIGNIFICANTLY. However, when DPS users attach images such as what i have done below, DPS bandwidth will be utilized at very very much more extent that will slow down other viewers (as an image is usually a few hundred to few thousands times HEAVIER than a dps web page - to bandwidth taken for 1 viewer to see an image equal to 500~1000 viewer vewing a forum page without images).Think of multiplication effect when multiple users doing the same.. The forum will always accessible by viewers, just they may have timing problem to download images if the images' source are in other server (flickr). This , however, untrue of they upload images to DPS server.
I strongly recommended that, whenever possible, upload your images to other websites (e.g. flickr , nikonclub, canonclub) to speed up the DPS web pages viewing..or otherwise, follow the admin advice to limit the size of image attached to this server.

The bandwidth to be considered isn't just from DPS as a provider but also the size of the data pipe to the user. Their browser will be able to cope with drawing data from multiple sources - if anything, it may speed things up as separate streams are downloaded in parallel - but it all has to fit through the capacity of their data connection.

Dial up connections may be less common but people frequently use wireless connections for the last leg of the journey, which can have a dramatic effect on speed (especially if they decide to sit in a awkward corner of their house or at the far end of the garden). Also, while for home use most of us have long ago given up paying much attention to the page size of different sites, it comes back to bite you when you have to pay (at rates that can be ridiculously expensive once you pass the "fair usage" cap).

Given that data access on the move also means that smaller screens are back with a vengeance, there are probably more reasons now to impose an image size limit than when it was first set. Of course, the sensible thing to do is to link to a larger version somewhere else so that, if someone wants, they can choose to see your image in all it's glory.

The FAQ is where you'll find most questions answered.

http://digital-photography-school.com/forum/faq.php?faq=img#faq_flckr

When you "Imbed" a photo it acts as a link directly back to Flickr.
