尝试解决其他人不太好的代码问题。任何想法将不胜感激。它似乎在引入图像的<cfif>轰炸：
<cfif LEN(qryCampers.std_image_filename[iRow + iCol]) GT 0>
如果我注释掉if（并且只保留与cfif语句中的“no_image.gif”相关的部分）我们就是好的。该文件出现。
CF Server 8，SQL Server 2000，图像尺寸相对较小（全部低于30kb，宽度不超过300px），此代码在某些时候有效，而且只需要，它需要FOREVER加载PDF。此特定查询（仅12条记录）导致错误。
错误：
Invalid image format

听起来这一行<cfimage source="../photos/#qryCampers.std_image_filename[iRow + iCol]#" action="read" name="cardImage">中找到的图像不是有效的图像格式。你确定它正在尝试阅读有图像吗？
答案 1 :(得分：1)
您是否尝试使用“isImage”？
<cfif trim(qryCampers.std_image_filename[iRow + iCol]) neq ''
AND isImage('../photos/#qryCampers.std_image_filename[iRow + iCol]#')>
我同意@Leeish的说法，CFImage标签正在获得一些它无法识别为图像的东西。我有时间有一个标记为jpg的jpg并且我可以在浏览器中查看它然后我试图在photoshop或类似的东西中将它拉出来我发现jpg本身存在aheader问题那是在阻止cfimage或cfx_ImageCR（我更喜欢）。
答案 2 :(得分：1)
就您的无效图片错误而言，我们遇到了类似无效格式和性能下降的问题。我们的解决方案是使用cfimage将图像转换为png然后再转换为jpg。我们是在图片上传时完成的，但您可以在您的情况下做同样的事情。
<cfimage source="#expandPath('\images\temp')#\#cffile.serverFile#" action="convert" destination="#expandPath('\images\temp')#\#cffile.serverFileName#.png" overwrite="yes">
<cfimage source="#expandPath('\images\temp')#\#cffile.serverFileName#.png" action="convert" destination="#expandPath('\images\temp')#\#cffile.serverFileName#.jpg" overwrite="yes">
