Unfortunately, I have no suggestions... instead I may add my session (presentation, of course differs from real session): In[1]:=Print[{MemoryInUse[], MaxMemoryUsed[]}] From In[1]:={1127248, 1160944} In[2]:=$Version Out[2]="4.0 for Microsoft Windows (December 5, 1999)" In[3]:=Print[{MemoryInUse[], MaxMemoryUsed[]}] From In[3]:={1129304, 1160944} In[4]:=Timing[imp = Import["ref24.jpg"];] Out[4]={20.93 Second, Null} In[5]:=Print[{MemoryInUse[], MaxMemoryUsed[]}] From In[5]:={22947160, 22952616}In[6]:= In[6]:=Timing[Show[imp];] Out[6]={288.58 Second, Null} In[7]:=Print[{MemoryInUse[], MaxMemoryUsed[]}] From In[7]:={22949256, 158176976} In[8]:=Timing[Show[imp];] Out[8]={353.99 Second, Null} In[9]:=Print[{MemoryInUse[], MaxMemoryUsed[]}] From In[9]:={22951256, 158179072} In[10]:=Timing[Show[imp];] Out[10]={408.53 Second, Null} In[11]:=Print[{MemoryInUse[], MaxMemoryUsed[]}] From In[11]:={22953240, 158181072} In[12]:=Timing[Show[imp];] Out[12]={418.47 Second, Null} In[13]:=Print[{MemoryInUse[], MaxMemoryUsed[]}] From In[13]:={22955256, 158183056} In[14]:=Timing[Show[imp];] Out[14]={418.48 Second, Null} In[15]:=Timing[Show[imp];] Out[15]={423.09 Second, Null} In[16]:=Print[{MemoryInUse[], MaxMemoryUsed[]}] From In[16]:={22958184, 158185968} In[17]:=Timing[Show[imp];] Out[17]={420.51 Second, Null} In[18]:=Timing[Show[imp];] Out[18]={430.46 Second, Null} In[19]:=Print[{MemoryInUse[], MaxMemoryUsed[]}] From In[19]:={22962600, 158189680} %%%%%%%%%%%%%%%%%%%%%%%%%%% Why so giant MemoryInUse = 22MB, and MaxMemoryUsed = 158 MB?! Why so large and variable Timing?! The file ref24.jpg is 50709 Bytes, and I've omitted output of Show, of course. Notebook itself when saved is only of 8358 B. Thanks, Zak %%%%%%%%%%%%%%%% %%%%%%%%%%%%%%%% Subject: [mg30211] Import a jpg/wmf file Author: Oliver Werther <oliverXXwerther at home.com> Organization: Steven M. Christensen and Associates, Inc and MathTensor, Inc. All, I import a 37kByte jpeg file... Timing[Show[Import ["name.jpg"]]] and it takes Mathematica 30 seconds to do this!? (25 sec. for a bmp file). - wmf is only supported for export. Any suggestions? thanks Oliver
